The pair said in a statement, "We are so grateful to report that our son Noah has been progressing well during his treatment and the doctors are very optimistic about the future for our little boy. He has been brave throughout and we continue to be inspired by his courage. We thank God for the strength he has given all of us."

"Our gratitude to his doctors and caretakers cannot be put into words. We'd also like to thank the thousands of people that have sent their prayers and good wishes to us,” the couple added. "As we continue this journey, we are greatly comforted by your support and love."

Bublé and Lopilato have put their careers on hold since Noah’s diagnosis in November. At the time, the two said, "We are devastated about the recent cancer diagnosis of our oldest son Noah who is currently undergoing treatment in the US. We have always been very vocal about the importance of family and the love we have for our children.”
